Description
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application No. 62/633,951 filed 22 Feb. 2018. The entire contents
of the above application are hereby incorporated by reference as
though fully set forth herein.
FIELD
[0002] The present invention relates in general to catheter tubing.
More specifically, the present invention relates to a multi-tube
catheter tubing assembly device for a urinary catheter.
BACKGROUND
[0003] It is well known in the art that indwelling urinary catheter
systems, such as a Foley catheter consists of two lumens: (i) one
for drainage of urine from the bladder and (ii) a second lumen used
to inflate the retention balloon that lies within the bladder to
hold the catheter in place. A triple lumen catheter currently in
the art has an additional lumen for instillation of fluid into the
bladder. In place of the third lumen used to instill fluid, this
optional lumen may be used in order to continuously efflux fluid
and irrigate the periurethral space and the catheter body to
prevent formation of biofilm and further ensuing bacterial
infection. The fluid instilled generally includes certain
therapeutic agents used in intravesical therapy such as
immunotherapy agents or chemotherapeutic agents, antispasmodic
agents and numbing agents, such as lidocaine. The fluid effluxed
generally includes antiseptics, antibiotics or antimicrobials
and/or combinations thereof to prevent biofilm formation on the
exterior surface of the catheter body. Such a catheter system is
more fully described in patent application number PCT/US17/26450,
the contents of which are incorporated by reference herein.
[0004] While the use of a multi-lumen tubing system is preferred,
present systems known in the art utilize long separate catheter
tubes that connect each catheter lumen to its opposing end source,
whether it be the drainage container for the drainage lumen or the
fluid container used to instill fluid or irrigate the periurethral
space and catheter body. Often, these separate tubes have a
tendency to tangle with themselves and the patient's body and
become cumbersome for the patients and the medical staff while
treating the patient. It is therefore an object of the present
invention to provide a catheter tubing device assembly to reduce
tangling with other tubing or the patient's body.
BRIEF SUMMARY OF THE INVENTION
[0005] The preferred embodiment of the present invention comprises
a drainage tube and a fluid delivery tube, each having an exterior
surface and connectors on both its ends wherein the tubes are
bundled together by having a portion of the exterior surface of the
drainage tube is fixedly attached to a portion of the exterior
surface of said fluid delivery tube. In the case of multiple fluid
delivery lumens, the present invention anticipates having a
plurality of fluid delivery tubes wherein a portion of the exterior
surface each tube is fixedly attached to the exterior surface of
another tube in the assembly. The connector on the first end of the
drainage tube is operable to attach to a drainage lumen of a
urinary catheter, and the connector on the second end is operable
to attach to a container for holding the drained fluid. The
connectors on the first end of the fluid delivery tube(s) are
operable to attach to a fluid delivery lumen of a urinary catheter,
and the connector on the second end is operable to attach to a
container assembly for holding the fluid to be delivered. As an
additional option, the inside diameter of the drainage tube may be
greater than the diameter of any fluid delivery tube. Similarly,
the upper portion of the tubes between the catheter and attachment
portion is necessarily longer to prevent kinks in the tubing.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a side view of the catheter tubing device assembly
of the present invention showing a drainage tube and a plurality of
fluid delivery tubes.
[0007] FIG. 2 is a side view of the catheter tubing device assembly
of the present invention attached to a multi-lumen urinary
catheter.
DETAILED DESCRIPTION
[0008] Turning to FIG. 1, the catheter tubing assembly device of
the present invention is shown in detail and comprises a drainage
tube 10 having an exterior surface with a first end 20 and a second
end 30, and a plurality of fluid delivery tubes 40 each having an
exterior surface, a first end 50, and second end 60. In order to
prevent entanglement of these tubes, an attachment portion 70 of
the exterior surface of the drainage tube is fixedly attached to a
portion of the exterior surface of the fluid delivery tube 40 such
that the tubes form a bundle. The attachment portion 70 may be
prefabricated such that the assembly constitutes a contiguous body
or the individual tubes can be separately bonded together using
bonding means known in the art, e.g. adhesives, glues, or epoxies.
Although not shown in the figures, for this patent, the present
invention only requires at least one drainage tube 10 and at least
one fluid delivery tube 40, to be compatible with a typical triple
lumen urinary catheter. Moreover, as shown in FIG. 1, the drainage
tube diameter, i.e. the inner diameter of the tube, is necessarily
larger than the inner diameter of the fluid delivery tubes.
[0009] The drainage tube 10 has a first drainage tube connector 80
at its first end 20 and a second drainage tube connector 90 at its
second end 30. The fluid delivery tube 40 has a first delivery tube
connector 100 at its first end 50, and a second fluid delivery tube
connector 110 at its second end 60 operable to attach to a
container assembly known in the art for holding fluid that is to be
delivered.
[0010] Based on the multi-lumen design of the catheter, in order to
avoid kinks or looping in the entire catheter tubing system. the
upper portions 120 of each tube in the assembly, i.e. the length of
tubing between the first ends 20, 50 and the attachment portion 70,
is necessarily longer than lower portions 130 of each tube, i.e.
the length of tubing between the second ends 30, 60 and the
attachment portion 70.
[0011] Turning to FIG. 2, the embodiment of the invention displayed
in FIG. 1 is shown being used with a 3-way catheter as described in
patent application number PCT/US17/26450. This catheter is merely
illustrative of the general components of a 3-way catheter known in
the art and how the terminal ends of such a catheter are used in
combination with the subject catheter tubing assembly device. An
elongated tubular catheter body 601 having a distal end 602 and a
proximal end 603 is shown. A drainage lumen 604 extends through
tube 617 in the catheter body 601 from the distal end 602 to the
proximal end 603, and the drainage lumen 604 communicates with an
opening or eyelet 605 in the catheter body 601 at the distal end
602 of the catheter body 601 through which the fluid may flow into
the drainage lumen 604 when the catheter is used to drain a fluid
from a cavity, duct, or vessel (e.g., draining urine from a
person's bladder). A first sleeve portion 606 constructed from a
semipermeable membrane is formed over the catheter body 601. A
fluid delivery lumen 607 extends from the catheter body 601 at the
distal end 602. The fluid delivery lumen 607 connects with the
first sleeve portion 606 using tube 616 that runs through the
length of the catheter body 601. The fluid delivered into the
catheter body 601 through the tube may be continuously effluxed
from the sleeve portion 606 through the semipermeable membrane in a
circumferential controlled delivery to continuously irrigate the
periurethral space and the catheter body 601 to prevent formation
of biofilm and further ensuing bacterial infection. However, the
sleeve portion 606 is not required as the fluid may be used to
continuously or intermittently irrigate the bladder using a
traditional 3-way Foley catheter.
[0012] A second sleeve portion 609 constructed from a semipermeable
membrane is formed over the catheter body 601 above the tube
section 610. A second fluid delivery lumen 611 extends from the
catheter body 601 at the distal end 602. The fluid delivery lumen
611 connects with the sleeve portion 609 using tube 618 that runs
through the length of the catheter body 601. The fluid delivered
into the catheter body 601 through the tube 618 is continuously
effluxed from the sleeve portion 609 through the semipermeable
membrane and into the bladder itself.
[0013] The first drainage tube connector 80 is operable to attach
to the cylindrical drainage lumen 604 by using attachment means
known in the art, including using an open-ended cylindrical cap, as
shown in the figure, that is force fitted over the drainage lumen
604. The second drainage tube connector 90 is operable to attach to
a container assembly known in the art for holding fluid that is
drained by using attachment means known in the art, including using
an open-ended conically shaped cap, and shown in the figure, that
is force fitted within the inlet lumen for the drainage container
(not shown).
[0014] The first fluid delivery tube connector 100 is operable to
attach to the terminal ends of the fluid delivery lumens 607, 611
and the second fluid delivery tube connector 110 is operable to
attach to a container assembly known in the art for holding fluid
that is to be delivered (not shown). The first and second delivery
tube connectors 100, 110 are selected from a group of pressurized
connectors known in the art, including but not limited to
male/female locking mechanisms, such as Leur locks. The terminal
ends of the fluid delivery lumens 607, 611 for a urinary catheter
may be male or female. In FIG. 2, the first delivery tube connector
100 comprises a female connector that attaches to the male terminal
end of the fluid delivery lumen 607, 611 and the second fluid
delivery tube connector 110 comprises a male connector that
attaches to the inlet lumen for fluid container (not shown).
[0015] Obviously, the bundling of multiple fluid delivery tubes 40
makes it difficult on the user to make sure that the connectors
100, 110 of each tube are attached to the proper catheter lumen and
fluid delivery container. In order to prevent such a problem, the
present invention optionally may include a marking system on its
connectors 100, 110 so that the user can easily distinguish the
connectors 100, 110 of one fluid delivery tube 40 from another when
making necessary connections. Such markings on the connectors may
be made by using different colors, alternative fitting
configurations, or different inscriptions on the fitting connector
itself, or any other comparable marking mechanism known in the
art.
[0016] Although not shown in the figures, the invention anticipates
having sufficient length and space on each individual fluid
delivery tube 40 to accommodate a roller clamp. These clamps are
well known in the art and are used to adjust the volumetric flow of
fluid through the catheter by adjustably clamping the flexible
catheter tubing. For the present invention, the roller clamp would
be positioned around an exterior portion of the tube either before
or after the attachment portion 70 of the tube 40 that is fixedly
attached to another fluid delivery tube 40 or drainage tube 10.
[0017] For the purposes of promoting an understanding of the
principles of the invention, reference has been made to the
preferred embodiments illustrated in the drawings, and specific
language has been used to describe these embodiments. However, this
specific language intends no limitation of the scope of the
invention, and the invention should be construed to encompass all
embodiments that would normally occur to one of ordinary skill in
the art. The particular implementations shown and described herein
are illustrative examples of the invention and are not intended to
otherwise limit the scope of the invention in any way. For the sake
of brevity, conventional aspects of the system (and components of
the individual operating components of the system) may not be
described in detail. Furthermore, the connecting lines, or
connectors shown in the various figures presented are intended to
represent exemplary functional relationships and/or physical or
logical couplings between the various elements. It should be noted
that many alternative or additional functional relationships,
physical connections or logical connections may be present in a
practical device. Moreover, no item or component is essential to
the practice of the invention unless the element is specifically
described as "essential" or "critical". Numerous modifications and
adaptations will be readily apparent to those skilled in this art
without departing from the spirit and scope of the present
invention.
